How to write shareware programs?

[anilkumarby]

Hi people,

I had written a tool for which I need to make it a trialware
or a shareware. It should work for 90 hours and later has to prompt
for registration. How to do this ?
Which language should I use : VC++/VBasic/Delphi etc ?

Thanks and regards
Anil

The time lock should be built-in to whatever program your making. So if the shareware is a C++ program so too will be it's time lock. It doesn't really matter what language you use to create the program. Anyone who wishs to crack it will read the program's "machine code" to first understand how it works and then to patch it. So it's not a matter of security just a matter of what code you feel the program runs best in.


EDIT Go here for some timelock products. Most coding examples are written in C++ but can be found with a little searching.
